OILING SYSTEM roa AUTOMOBILES.

Specification of Letters Patent. Patented Nov. 15, 1921 Application filed June a, 1920. Serial 1%. 382,562

Be it known" that 1, AUGUS a citizen of the United states residlng at -Medford, in the county of Middlesex and State of Massachusetts, have invented new a and useful Improvements in Oiling Systems for Automobiles, of which the following is a specification.

This invention relates to an improved crank case and lower cover therefor, the same; being particularly adapted for use in Ford automobiles.

In such automobiles the crank caseis provided with a cover on the bottom thereof, said cover having three recesses or chambers therein constituting splash cups, spaced apart and in alinement with three of the cranks of the crank shaft; so that as the l crank rotates these cranks project into the chambers whilepassing through. the lower arc of their movement and thus distribute theoil. a. l l a The oil which is supplied to said chambers is carried from anoil reservoir bythe flywheel of the magneto located at the rear of ward the front of the crank case and which delivers the oil to the crank case at the front end. The oil passes into the first of said chambers in alinement with one of said cranks and saidicrank passes through said chamber and splashes a portion of the oil out of the chamber and overfinto the second chamber and from the second chamber it is inlike manner fed or carried over to the third chamber and fromthe third chamber it is in like manner carried over into the oil reservoir. l

It has been found in practice that this method of distributing the oil-is defective in thatthe first chamber referred to may be full of oil while the second chamber has less oil than the first and the third chamber has less oil than the second and it is therefore the object of this invention to provide a construction whereby the oil will stand at: substantially the same level in each of said chambers and, furthermore, it is the object of this invention to provide a means where by the height of the oil in said chambers may be regulated. By thesemeans the uneven amount and over abundance of oil sup ply at the front of the crank case is carried to the other chambers and the amount of oil supplied to each connection rod is I. JoHNsoN,

shown in dotted lines in connection therewith. l

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 isthe crank case. 11 1s a cover fast to the bottom of said crank case and provided with splash cups or chamhers 12, 13 and 14. 15 is theoil reservoir into which the magneto fly-wheel 16 pro jects and carries oil therefrom upwardly delivering the same to a pipe 17, which is inclined downwardly and delivers theoil at the front end of the crank case Where it runs into the chamber 12. The chamber 12 is provided in the bottom thereof with a plurality of holes 18 which lead into a conduit 19 extending longitudinally along the bottom" of the crank case cover 11, the same being connected by holes 20 and 21 to the chambers 13 and 14' respectively. The con-.

duit 19 has a branch 22 which extends at right angles to the conduit 19 and which has an outlet 23 into which is screwed a hollow plug 24. Theplug 24 is provided with a hexagon head 25 and projects through a .T".

shaped connection 26 which has anannular chamber 27 therein which opens into a passage 28 in the branch 29 of saidT-shaped connection. The plug 24 has outlet ports 30 oppositely disposed and leading from the interior 31 of said plug into the annular chamber 27,. whereby said outlet ports connect said conduit to said annular chamber 27 and passage 28.

The branch 22 of the conduit 19 has an upwardly extending-projection 32 in which is located the outlet 23 and between the upper end of said projection, see Figs. at and 6, and the'T-shaped connection 26 is located a washer, 33. By screwing down from the stud 24 the parts 26, 32 and 33 are firmly clamped together.

It is evident that the height of the oil in the diiferent chambers 12, 13 and 14 willbe regulated by the height of the ports 30 and to enable'the height of said ports to be varied washers of different thicknesses or a r plurality of Washers may be interposed between the projection 32 and the connection 26. The connection '26 is connected by a union 34: to an outlet pipe 35 which leads [into'an elbow 36 to which it is connected by a unioni37,the elbow 36 leading into the bottom of the oil reservoir .15.

chamber 12 it flows through the holes 18 into the conduit 19" and from the conduit 19 through the holes 20and 21'it flows into the chambers 13 and 14.

The height of the oil is kept the. same in thechambers12, 13 and 14 by means of the branch 22 and plug 24, the oilflowing from the branch 22 through the interior port 31 of the plug 24- and outwardly through the ports 30 into the outlet pipe 35, whence it returns through the elbow 36 to the reservoir 15. I V I cla1m: 1. A crankcase'for automoblles having a plurality ofjchambers for oil in the bottom thereof, a reservoir for oil. a rotary member adapted to project into saidreservoir, a pipe leading downwardly from said rotary memberto one of said chambers, whereby oil ma-ybe fed from said reservoir to said lastnamed-chamber, a supply conduit opening into the botto'm of each of said chambers and connecting them to each other and an overflow; pipe "extending upwardly from said conduit above "said chambers and thence downwardly'to said reservoir. r

'12 ."A"crank case for automobiles having a plurality of chambers for oil in the bottom 6 thereof, a reservoir for oil, rotary member adapted to pro ect into sald reservoir, a pipe vleadin'g'downwardly from said rotary member to one of said chambers, whereby oil may be fed fromsaidreservoirto said last-named chamber, a supply conduit opening into'the bottomtofieachof gsaid chambers and con nectingthem to each other, an overflow pipe extending upwardly from said conduit above said chambers and thence downwardly to said reservoir and means in said overflow pipe adapted to regulate the level of oil in said chambers.

3. A crank case for automobiles having a plurality of chambers for oil in the bottom thereof and having a reservoir for oil, a conduit opening into each of said chambers and connecting them to each other, an overflow pipe leading form said conduit to said reservoir, there being an outlet port leading from said conduit into said overflow pipe, and means to adjust the level of thebottom of said port vertically, whereby the level of the oil in said chambers may be regulated.

4-. A crank case for automobiles having a plurality of chambers for oil in the bottom thereof and having a reservoir for oil, a conduit opening into each of said chambers and connecting them to each other, an overflow pipe opening at one end thereof into said reservoir, a connection attached to the opposite end of said overflow pipe and provided with an annular chamber, a hollow plug connectingsaid last-named connection to said conduit, said plug being provided with an outlet port leading from the interior thereof into said annular chamber and having screw-threaded connection with said conduit, whereby said connection may be clamped to said conduit.

5. A crank case for automobiles having a plurality of chambers for oil in the bottom thereof and having a reservoir for oil, a conduit opening into each of said chambers and connecting them to each other, an overflow pipe opening at one end thereof into said reservoir, a connection attached to the opposite end of said overflow pipe and provided with an annular chamber, a. hollow plug connecting said last-named connection to said conduit, said plug being provided with an outlet port leading from the interior thereof into said annular chamber and having screwthreaded connection with said conduit, whereby said connection may be clamped to said conduit, and a washer interposed between said connection and said conduit. whereby the level of the bottom of said port may be adjusted vertically and the level of the oil in said chambers may be regulated.

In testimony whereof I have hereunto set my hand 1n presence of two subscribing witnesses.

AUGUST IVAR JOHNSON.
